MOLD FOR SECURING SCREEN-WIRE.

To all whom it may concern:

Be it known that l, CLAUDE C. BRooKs, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and State of Missouri, have made certain new and useful Improvements in Molds for Securing Screen-Wire, of which the following is a specification.

This invention relates to screen wire molds, and one of the principal objects of the invention is to provide a moldwhereby screen wire may be detachably secured, and

held in stretched position, on doors, windows, screen frames, sleeping porches and other places where wire-screens'are desired, the mold itself adapted to be formed into a frame.

Another object of the invention is to provide a mold including a-base portion provided with means for attaching wire thereto, and a top portion adapted to interlock with the base portion for clamping the wire between them, the wire attaching means also serving as means for clamping the top to the base portion.

A further object of the invention is to provide a wire screen mold of the class described, which will be extremely simple, durable, efficient in operation and inexpensive to manufacture, and which may be made to sell at a low price.

With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts herein after more fully described and claimed, and illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the several figures, of which- Figure 1 represents a plan view of the device illustrating its manner of operation, Fig. 2 represents a vertical transverse sectional view taken on the plane indicated by the line 22 of Fig. 1, Fig. 3 represents a perspective view of a portion of the top mold, and Fig. 4 represents a perspective view of a portion of the base mold. Fig. 5 represents a perspective view of one corner of a wire frame formed of the mold.

Referring more particularly to the drawing, the device includes a base mold A and Specification of Letters Patent.

Application filed May 15, 1914. Serial no. 888,710.

a top mold B, each formed of a strip ofsheet metal bent to shape, the base mold comprising a bottom 5 and a rear wall 6, which extends upwardly from the rear edge of the bottom, and overhangs said bottom, at an inclination thereto of about 45, the front edge of the bottom being overturned up- Wardly to provide a flange 7, which flange has struck up therefrom at spaced intervals a plurality of teeth or prongs 8.

The top mold comprises a body portion 9 whose lower edge 10 is bent at right angles thereto to provide a base flange, and whose upper edge is bent in a direction opposite to the base flange and is disposed at about an angle of 45 with the body portion to pro vide an inclined front wall 11.

The operation of the device may be briefly described as follows:' The base mold is secured to one side of the screenframe or other object to which the wire netting is to be secured, said object being indicated in dotted lines, as at 12, the base mold adapted to be secured. thereto by screws, nails or tacks or bolts or rivets, or if the object is metallic to be soldered thereto, and

one edge of thewire screen indicated by the numeral 13 is placed with its extreme edge 14 at the junction of the bottom 5 and rear wall 6, and the screen may be then pressed down over the prongs 8, which are disposed nearly at right angles to the bottom, as indicated in dotted lines at 8*, and the top mold B is then placed upon the base mold over the edge portion of the. wire in a manner indicated in Fig. 2, with the base flange of the top mold engaging the outer edge of the wire and being disposed above said wire at the junction of the rear wall and bottom of the base mold, the body 9 of the top mold when in this position being engaged against the upper edge of rear wall 6, and the lower edge of the front wall 11 engaging the wire in a line parallel with its edge and holding it against flange 7 in the line of the junction points of prongs 8 with that flange. The prongs 8 are then at intervals bent down upon the outer face of front wall 11, thereby clamping the top mold against the base mold, for securely holding the wire edge. By this construction it will be evident that prongs 8 first serve the purpose of attaching the wire to the base mold,- and subsequently of clamping the top mold upon the base mold. One edge of the wire screen having been secured to the object in the manner described, the opposite edge of the object is provided with a base mold, and

the wire is then stretched and engaged over the prongs of the last mold and the second top mold is then clamped upon the wire in the manner previously described. The remaining edges of the wire may be secured in the same manner.

By the use of my invention, it will be readily understood that doors, windows, screen frames and other objects of the like nature, can .be screened in a short time, and that the wire can be stretched in the operation and securely held in stretched position, and it will be further understood that one of the great advantages accruing to the invention is the fact that the top mold. may be quickly removed and worn out wire taken off and replaced by new wire, thus eliminating the trouble, loss of time and expense of skilled labor often incident to the removal of old wire and replacing of new wire where the ordinary forms of screen molding are used.

A11 efiicient and strong screen frame, a corner of which is illustrated in Fig. 5, could be. made of a number of base molds welded, soldered or otherwise secured together and the wire netting could be secured by sections oftop mold in the manner already set out.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination and arrangement of parts thereof, as do not depart from the spirit of the invention and the scope of the appended claims.

I claim:

1. A device of the class described including a base molding adapted to be secured to an object, said mold comprising a flat bottom, a rear wall formed on one edge of said bottom and overhanging the same at an angle of about 45, a flange formed on the opposite edge of the bottom and doubled thereupon, prongs struck up at intervals from said flange, said prongs adapted to engage the edge portions of a screen wire, and a top mold comprising a body portion, having one edge bent at right angles to provide a base flange, and having its opposite edge bent at an acute angle and oppositely to the base flange to provide an inclined front wall, said top mold adapted to be disposed upon the base mold with the base flange upon the edge of the wire at the junction of the rear wall and the bottom of the base mold, and with the upper edge of the rear wall abutting against the body ortion of the top mold, and with the front edge of the front wall engaging over the Wire along the line of the junction points of the prongs with said flange, said prongs adapted to be bent upon said front wall for clamping the molds together.

2. A device of the class described comprising a base mold adapted to be secured to an object, said mold including a bottom, having its rear edge bent upwardly at an angle to form a rear wall inclined relatively to the bottom and overhanging the latter, the opposite edge of the bottom being returned thereupon to form a flange, prongs struck up at intervals from said flange, said prongs adapted to be engaged by a wire screen, and a top mold adapted to co-act with the base mold for clamping the said wire screen, said prongs adapted to be bent .upon the top mold for clamping the molds together.
